HOUSTON, November 26, 2018 (PCW) -- Chevron Phillips reported flaring at its Sweeny 24 olefins unit in Old Ocean, TX following a small fire on Thursday at an oil lubrication line. The company noted in a TCEQ filing that the unit's furnaces and a cracked gas compressor were shut.

The unit, which has an ethylene capacity of 1.5 billion lbs/yr, experienced a process upset the previous Tuesday due to an unexpected loss of steam supply. That event also affected the site's Sweeny 33 olefins unit. A third olefins unit at the site, Sweeny 22, has been shut since May. --
